I know I've seen this addressed before, but now we have our 19' and setting it up, so maybe it will sink into my brain.
What is experience of putting Command hooks on vinyl liner and on "wood" paneling?
Has anyone removed later and seen long term results to surfaces?

We used a Command hook in the kitchen to the left of the window on the door frame. I was scared to stick them on the wood so we purchased this and installed it on the front wall of the bathroom in the dinette area.

In the bathroom so far we have used power lock suction items and I am thinking we will continue to stay that way.
If you search "power lock suction" they have all kinds of things for the bathroom. You can also stick them to the trailer outside to hang towels and things.

I'm using Command hooks exclusively. I've had no problem removing and placing them in another location. However, I haven't moved one in a long time, so I can't say what might happen over time. I'm not anticipating a problem.
The MOST important thing you can do is READ and SAVE the instructions. If you follow those, you should not have a problem. If you don't, you will tear the vinyl.
I bought the cheap white plastic versions initially and ended up replacing them all ( except in the bath ) with brushed nickel.

Make sure you use the "power lock" type. They have a lever that sucks them to the wall. We have had them on since September and one trip to Florida and it takes me a second to get them off if I want to move them.

I copied the wrong thing above and cannot change it but those are cool too. This is what we put on the front bath wall.

We have the power locks with the lever, and like most of the reviewers on Amazon, have had zero luck with them staying on. We have one of those Umbras by our door and am considering putting one on the outside of the bathroom wall if I can find enough stud area to drill into.

We have a mirror, towel rack, and tooth brush holder and I have had no problem. I just wet them a little, push hard and flip the lever. Even the mirror stayed on the wall during a 1300 mile trip which I was surprised.
